BENJAMIN LAI/traer, oF osixosm WIsGoNSlN-- yreprisals Y 'TRACK CONSTRUCTION# Application 'led 'January 17,1927.l Serial N o. 1613633.

The invention relates to a track construction, and more particularly to track construction for usein connection with motordriven vehicles. j

Where trucks carrying heavy loads are used on softground as, Afor instance, in concrete highway constructionwhere supply trucks for bringing the aggregates to the mixer have to pass over thev subgrade to deposit-their loads either into the loading skip of the mixer oradjacent thereto, this subgrade, because of the weightfof'the rtrucks and the frequentdamp or muddy condition of the soil, does not provide a good foundation for the trucks'and soon becomes badly rutted so that great diiiiculty is experienced n in getting the trucks to the unloading point. The-object of this invention is to provide va demountable or sectional track construction, upon which the trucks may be driven over soft ground such as above noted, wherein each line of the track 'consistsof a plurality of track sections which are secured'together at their ends and Vare spaced apart to suit .j the wheel gauge of the" trucks by spacing vmembers removably connected with the track sections. l' The invention furtherlconsists in the several features hereinafter set forth and more particularly Vdefined by claims at the conclusion hereof. Y' l In the drawings Fig.V lis aside elevation view of a portion of a sectional track embodying the invention; Y f

Fig. 2'is ay plan view thereof, broken away' t Fig. 3 is a perspective end viewV of one of the track sections associated with a spacing Vmember; l i 4 Y Fig. 4 is a section taken on the line 4 4. of Fig.2;"v y fr `l kFig. v5 is 4a detail sectional view taken on the line 5-5 of Fig.

parts being `In the drawings the numeral `7 designates l the track sections. Each 'ofthese track sec? tions is preferably -formedfvof sheet metal,V such as heavy boiler-ironfwliich:is stamped or otherwise suitably Vformedinto a wheel.- rcceiving channel sectionS Ahaving reinforc-V ing flanges 9 projecting laterally from the iianges of the channel yandears y10 which are welded or otherwise suitably secured tothe side flanges of the channel section 8 and the reinforcing 'flanges 9 and provided Vwith 'holes 11. 1 Y

i Adjoining sections of thetrack are secured this invention.

j vents' spreading of the lines of Vin alined position by angle brackets 12 of sheet metal mounted on a'support 13. Each of the angle brackets consists of a base portion 14, a vertically extending portion 15 and a bifurcated flange portion 16 with a vertically disposed' -slot 17 between the `bifurcations and extending down into the-vertical portion- 15. On one side of the track these angle members may be -iiXedly secured to thesupport 13 in Vany suitable manner-,as by` rivets '18. On the other side of the track, in order to adjust the tracks to Vtrucks of different wheel gauges, it is preferred to se# cure the base portions 14 of the angles lin spaced relation to each other and relative to the other .slide of the track by 'means of f func-tion ofy acting as a tie bet-weeirthe brackets 12 oneach side of the` track and as a spacing means for the tracks, it will be understood that separate bars, similar to supports 13, canbe used to space'the sides of the track apart .without departing from Furthermore, it will 'be understood that the supports 13A are not load supports for the track Vas they have 'a relatively smallbearing area and the weight of the truck `is taken by the track sections themselves,the Width lof the channel being sufficient to vreceive the wheels therein'.V

The .adjoining track sections are secured to the brackets 12 by the interiitting relation of the.v side 4portions ofthe channel 8 with the vertical portions 12 of the brackets,

-the disposition .of the ears againstvthe' inner sides of the bifurcations V16, and by pins 21 or other' suitable fastening means which pass through the holes n11 of the adjoining track sections,fand preferably have a clamping engagement with the under side ofthe bifurcations 16, these'pins 21 preferably having aslight taper so as to securea goed lit :and to accommodate' for possible slight inaccuraciesof alinement bef.

tween Jhe adjacent track sections The engagement ofthe ears Y1.0'3viith, the

brackets 12 prevents longitudinaldisplacement of the track sections relative to each other and the connection of these sections with the spacing members 13 through the angle bars 12, in the present instance,'pre

the track relative to each other. f

ln arranging the device lor use the spacinev members i3 are laid upon the subgrade or the sott soil Q2, at appropriate intervals, and the track sections T are placed so as to bring' their ends oit the channel between the spaced brackets 1Q, with the ears 1 0 in position, and the pins 2l are then driven into place, with the result that a track oit sullicient bearing; suritaee ttor the wheels 23 ot a truck 2l is provided to enable the truck to negotiate the sott ground and deposit its load, as lfor instance, into a skip oit a mixer.

l, t'lesire it to be understood that this invention is not to be limited to any particular torni or arrangement ot parts except in soil'ar as such limitations are specified in the claims.

That I claim as my invention is:

1.71411 a track ecmstructicn, the combination oit a plu ality ol anpled track sections` 'ier wheel vehicles, angled connectors interlocking" with adjacent ends oi? said track sections to prevent `lonlcitudinal displacement tlicreoit, and means tor preventing; lat eral displacement ol' said track sections.

In a track construction, the combination ot a plurality et channel-shaped track sections having;- laterally extendingl flange portions at each end, and spaced brackets between which each oi" the channel sections of adjoining;1 track sections is disiiiosed and having liann'es ei'ig'ageable with the ilangres oi said track sections to prevent longitudinal increment ot said track sections.

9. ln a track construction, the eoinbination ot a plurality ot rail members termed to constitute a track tor motor vehicles, said members haring ears at their ends, connecting .means between adjoining track sections having` parts engrageable with said ears to prevent longitudinal displacement otl said track sections, and means .tor prevelitinf` 'lateral displacement ot said track sections.

a. ln ay track construction, the eoniliination ot a pluralityv olf angled track sections harina' laterallyv extending ilange portions` at each end, spaced brackets between which raeh ol" the sections oi adjoining; track sections is disposed and having' iianpes engage able with the flanges oi: said track sections to preventl longitudinal movement ot said track sections, and means associated with said brackets and the flanges oit said track sect-ions lor iirnily holding said sections to said brackets.

Lesa-,sse
